SECTIONAL-DOOR CONSTRUCTION.

Specification of Letters Patent.

Patented Jan. 25, 1921.

Application filed July 14, 1920. Serial No. 395,067.

To all whom it may canoe-m:

Be it known that I, PERRY J. Mvnns, a citizen of the United States,residing at Col-leyville, in the county of Montgomery and State oiKansas, have invented certain new and useful Improvements inSectional-Door Construction, of which the tollowing is a specification.

The invention relates to a sectional door construction and moreparticularly to the class of grain car doors.

The primary object of the invention is the provision of a door of thischaracter wherein the same is formed in a plurality of sections adaptedto be supported for movement selectedly whereby the doorway with whichthe door is associated can be fully or partly opened or closed and whenthe sect-ions are moved to open position they will be suspended overheadyet the same may be readily accessible for the closing of the doorway.

Another object oi the invention is the provision of a door-0t thischaracter wherein the hangers for the sections thereof are of novel formandconnected with a doorway in a novel manner so as to permit easy andconvenient shifting of the sections of the door for the opening andclosing thereof, and said door when in a closed position will constitutea tight closure so as to prevent the leakage of grain from the railwaycar or other container for the grain, and by reason of the constructionand arrangement the sections can be manipulated without excessive timeand labor ordinarily required in the opening and closing of a doorstructure.

A further object of the invention is the provision of a door of thischaracter wherein the sections when in closed position can be firmlyfastened together without possibility of displacement resultant fromvibra tions incident to the travel of the car, the door beingspeciallydesigned for use in grain cars.

1 A still further object of the invention is the provision of a door of:this character wherein the construction thereot renders the sameextremely simple, thoroughly reliable. and efiicient in purpose, strong,durable and inexpensive to manufacture and install.

lVith these and other objects in view the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter fully described, illustrated in the accompanying drawingsand pointed out in the claims hereunto appended.

In the accompanying drawings Figure 1 1s a fragmentary elevation looking"from the outer side of a railway car showing the door construction inaccordance with the invention applied and in closed position.

Fig. 2 is a. fragmentary vertical transverse sectional view, thesections of the door being'shown by full lines in closed positions andseveral of the sections shown by dotted lines in open position.

Fig. 3 is a fragmentary vertical transverse sectional view showingseveral ot the sections of the door about to be locked in closedposition.

Fig. t is a view similar to Fig.3 showing the sections closed andlocked.

Fig. 5 is an enlarged sectional view on the line 5-5 of Fig. 1 lookingin direction ot the arrows.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawings.

Referring to the drawings in detail A designates a portion of the baseor sill and B the vertical stiles of a doorway formed in the side of thebody of a railway car. Arranged. upon each vertical stile B on the tacenext to the doorway and extended above the same interiorly ot the bodyoi? the car heneath the roof thereof is a guide strip, preterably madefrom an L-shaped beam having its base flange 10 secured in any suitablemanner, while the guide flange 11 is at right angles thereto projectingoutwardly of the doorway.

Movable relative to the guide strips is a door comprising aplurality ofboard sections 12- each having fixed to its outer tace adjacent to eachend a hanger including a rigid strap l3 secured transversely "of thesection 12 and a pair of spaced hook-like horns '14-. and 15respectively, the horn 15 being disposed at an acute angle to the strap13 while the born 14: is at right angles there to and the bills 16 ofthese horns engage with the flange 11 ot the guide strip so that in thismanner the sections 12 of the door are slidably connected to said guidestrips whereby the sections can be shifted from the position shown byfull lines in Figs. 1 and 2 of the drawings to the positions shown bydotted lines in Fig. 2. It will be. clearly apparent that when thesections 12 are shifted to open position as shown by dotted lines in CirFig. 2 the same can be closely nested so as to occupy a minimum or theleast possible space when the doorway is open and on the shifting of thesections to closed position as shown in Figs. 1 and 2 the said sectionswill be superimposed perpendicularly edge to edge relative to each otherthereby constituting a tight closure for the doorway.

,The angular disposition of the horns 149 and of the hangers enables theside hangers to accommodate themselves to the curvature in the guidestrips when the door sections are moved from the perpendicular extent 01said strips to the horizontal extent thereof or vice versa.

Mounted on the outer faces of the sections 12 of the door intermediatelythereof in vertical alinement are interlocking members 17 and 18respectively, the member 17 being formed with an oil -set keeper end 19,while the member 18 is extended to form a latched end 20 to engage underthe keeper end 19 when the adjacent sections of the door have theirmeeting edges brought together. The member 18 is formed with an open eye21 while on the keeper end 19 is pivoted a hand operable lever 22 inwhich is hinged an eceentrically movable link 23 the latter beingadapted for detachably engaging in the open eye 21 and on the swing ingof the lever downwardly and inwardly in parallelism with the door theadjacent sections 12 thereof will be drawn tightly together and lockedand in this manner the said sections of the door are securely held inclosed position for closing the door ay in the side of the car.

iV hen it is desired to open any of the sections the lever is swungoutwardly and upwardly so that the link can be disengaged from the openeye 21 thereby freeing the adjacent sections from each other and onsliding these sections upwardly on the guide strips to a positionoverhead interiorly of the car body the doorway will be open and thedoor'when in open position will be out of the way thus avoiding anyinterference in the filling or emptying of thecar.

It is of course understood that the door construction is adaptable forother containers and this is contemplated within the scope of theinvention. I

From the foregoing it is thought that the construction and manner ofoperation of the door will be clearly understood and therefore a moreextended explanation has been omitted.

What I claim is:

1. In a door of the character described, a plurality of board likesections, angle strips arranged vertically and horizontally at oppositesides of a doorway and having intermediate curved portions joining thevertical and horizontal stretches thereof, hangers secured to saidsections and having angular hook portions sli'dably engaged with theangle strips, one hook of each hanger being of less length than theother hook and disposed angularly' relative thereto for permitting thesections to be overlapped when the hangers are moved on to thehorizontal portions of the angle strips for the close nesting of saidsections.

2. In a door ofthe character described, a plurality of board likesections, angle strips arranged vertically and horizontally at oppositesides of a doorway and having intermediate curved portions joining thevertical and horizontal stretches thereof, hangers secured to saidsections and having angular hook portions slidably engaged with theangle strips, one hook of each hanger being of less length than theother hook and disposed angularly relative thereto for permitting thesections to be overlapped when the hangers are moved on to thehorizontal portions of the angle strips for the close nesting of saidsections, and means carriedby the sections for interlocle ing engagementwhen said sect-ions aie brought to closing position.

in a door of the character described, a plurality of board likesections, angle strips arranged vertically and horizontally at oppositesides of a doorway and having ii'itermediate curved portions joining thevertical and horizontal stretches thereof, hangers secured to saidsections and having angular hook portions slidably engaged with theangle strips, one hook of each hanger being of less length than theother hook and disposed angularly relative thereto for permitting thesections to be overlapped when the hangers are moved on to thehorizontal'portions otthe angle strips for the close nesting of saidsections, means carried by the sections for interlocking engagement whensaid sections are brought to closing position, and clamps cooperatingwith said last named means to fasten the sections closed.

In testimony whereof, my signa ture hereto.
